Yes! I used my SW Visa to buy $150 in Amazon gift cards tonight. (Dh found struts for my car cheapest on Amazon!) So, when both cars get empty at the same time, we'll take them and get $.60/gallon off just from that.
With gas at $4/gallon and me driving 120 miles a day to/from work, we need all the discounts we can get!
I thought the ads said you had to use your Kroger credit card to get the bonus points. We went out to eat at a chain restaurant and stopped at the Kroger in the same shopping plaza to buy a gift card before dinner. It's easy enough.
